性能描述
mp 95-98.5 °C(lit.)
Biochem/physiol Actions
Inhibits induction of macrophage nitric oxide synthase.
Caution
May form insoluble oxidation products in storage. Sensitivity in colorimetric copper determination not usually affected.
Application
Spin trap used in conjunction with Fe2+ to detect NO in brain, kidney, liver, and other tissues. Simultaneous direct measurement of NO* and pO2 has been reported. A copper chelator, it has been used to quantitate copper in biological materials by ESR and is an inhibitor of superoxide dismutase, ascorbate oxidase, and other enzymes.
溶解性：易溶于水，溶于乙醇、甲醇、丙酮，不溶于乙醚和苯。水溶液呈碱性并逐渐分解。遇酸能分离出二硫化碳而使溶液混浊。
铜的显色反应；比色测定中提取少量重金属如铜、镉、钒、镍和钴
